Cygwin using 1-root User login

Set the root user login in Cygwin

To simulate a Linux environment in Windows, you can install Cygwin. After the Cygwin is installed, the system defaults to the login name of your Windows user name as Cygwin. Permissions are still ordinary users, to see whether the real root, just to see the command prompt is not "#", the average user is "$". , $ represents a normal user.

Workaround:

• Locate the Cygwin installation directory and have a file named passwd in the ETC folder

• administrator:unused:500:513:u-shucb\administrator,s-1-5-21-699659893-4255586547-1715211970-500:/home/the file in the Administrator:/bin/bash. Change to the following form:

  Root:unused:0:0:u-shucb\root,s-1-5-21-699659893-4255586547-1715211970-500:/home/root:/bin/bash

• In the home folder, you can see the Administrator folder and create a new root folder

• Run Cygwin again, #表示已经是root权限用户.

Open passwd This file with notepad++, find the following section and change the Windows user name to root (a total of 3).

Replace administrator to root, this is just renaming, the real key part is the red number part, that is the permission control, the 500 and 513 are changed to 0, so as to get the real root permissions.
